ANRe-M1: a GPU-accelerated numerical relativity code with multi-energy M1 neutrino transport
Takami Kuroda, Masaru Shibata
We present ANRe-M1 (Accelerated Numerical Relativity code with multi-energy M1 neutrino transport), a performance-portable, GPU-accelerated code for multidimensional core-collapse…
Nucleosynthesis in the Accretion-induced Collapse of magnetised, Rotating White Dwarfs
Laurenz Thümmler, Takami Kuroda, Masaru Shibata
Accretion-induced collapse (AIC) of a rotating oxygen-neon-magnesium white dwarf (WD) is an alternative channel of neutron-star formation, in which a mass-accreting star near the C…
A formation scenario of black hole-envelope systems --viscous hydrodynamics simulation in general relativity--
Alan Tsz Lok Lam, Masaru Shibata, Kenta Hotokezaka +1
By performing a viscous hydrodynamics simulation in general relativity for super-Eddington accretion flows onto massive black holes of mass --, we discuss a fo…
Accretion-powered flares from black hole-disk collisions in galactic nuclei
Joaquin Pelle, Kyohei Kawaguchi, Masaru Shibata +1
Black hole impacts on accretion disks in galactic nuclei can power luminous transients, but predicting their observable signatures is challenging because the post-collision flow is…
The hydrodynamics of stratified ultra-relativistic outflows and the origin of GRB X-ray plateaus
Gilad Sadeh, Kenta Hotokezaka, Masaru Shibata
The origin of the X-ray plateau phase observed in a large fraction of gamma-ray burst afterglows remains debated. We present a novel analytic framework for the hydrodynamics of ult…
Collapse of rotating very massive stellar cores leading to a black hole and a massive disk as a source of gravitational waves
Masaru Shibata, Sho Fujibayashi
We derive models of rotating very massive stellar cores with mass -- which are marginally stable to the pair-unstable collapse, assuming that the core is…
Neutrino pair annihilation driven jets from black-hole torus systems
Kyohei Kawaguchi, Sho Fujibayashi, Masaru Shibata
We perform axisymmetric general relativistic radiation-viscous hydrodynamics simulations of black hole (BH)-torus systems with full Boltzmann Monte-Carlo neutrino transport to inve…
Signatures of Exploding Supermassive PopIII Stars at High Redshift in JWST, EUCLID and Roman Space Telescope
Cédric Jockel, Kyohei Kawaguchi, Sho Fujibayashi +1
Recently discovered supermassive black holes with masses of at redshifts - in active galactic nuclei (AGN) pose severe challenges to our understandi…
Collapse of Rotating White Dwarfs and Multimessenger Signals
Takami Kuroda, Kyohei Kawaguchi, Masaru Shibata
We present results of numerical relativity simulations for the collapse of rotating magnetized white dwarfs (WDs) in three dimension, aiming at discussing the explosion dynamics an…
Variety of disc wind-driven explosions in massive rotating stars. II. Dependence on the progenitor
Ludovica Crosato Menegazzi, Sho Fujibayashi, Masaru Shibata +2
We assess the variance of supernova(SN)-like explosions associated with the core collapse of rotating massive stars into a black hole-accretion disc system under changes in the pro…
Multi-physics framework for fast modeling of gamma-ray burst afterglows
Vsevolod Nedora, Ludovica Crosato Menegazzi, Enrico Peretti +2
In this paper, we present PyBlastAfterglow, a modular C++ code with a Python interface to model light curves and sky maps of gamma-ray burst afterglows. The code is open-source, mo…
